Description
Technical field
A kind of analytical equipment of cigarette smoke chemical composition is the utility model is related to, it is more specifically a kind of to be used for directly
Measure the online and real-time analytical equipment of gaseous phase of main stream smoke of cigarette composition caused by the cigarette person's of smokeing panel test smoking cigarette.
Background technology
The relation research of cigarette smoke organoleptic quality and its chemical composition, it is the important research content of tobacco science and technology, not only
The material base formed for understanding cigarette smoke organoleptic feature has theory significance, and matches somebody with somebody for pointedly improving cigarette
Side, regulation and control cigarette smoke, so as to develop less harmful, the cigarette product of high-quality also there is highly important realistic price.For
The research of this aspect is carried out, traditional method generally requires is aspirated twice to same cigarette, i.e. smoking machine suction is rolled up
Cigarette and the cigarette person's of smokeing panel test smoking cigarette.Wherein, using the purpose of smoking machine smoking cigarette trapped under certain puffing regimenses
Cigarette smoke, and qualitative and quantitative analysis is carried out to its chemical composition；And the purpose of the cigarette person's of smokeing panel test smoking cigarette is to cigarette
